I Specification of Letters Patent. Patented J une 27, 1922,

Original application led April 25, 1919, Serial No. 292,767. Divided and this application led February 20,1922. Serial No.' 537,666. l

` To all whom it concern: o

Beit known that I, JOHANN SGHU'ETTE,

- l residing at Zeesen-Koenigs-Wusterhausen,

near Berlin, Germany, a citizen of the Republic of Germany, have invented certain new and useful Improvements in Pipe Joints; and I do hereby declare the following to bea full, clear, and exact description of the invention, such as will enable others skilled in the art to which it vpertains to vmake and use the same, this being a division from an application for a patent upon improvementsin pipe joints 'tiled by me on April 25th, 1919,

tubes. which are formed into framed or braced .girders and similar structures, such as are used in the framing of rigid airships, and especially tosuch joints as' are used in connection with the attachment of ties and braces to tubular members of such framing'. The structures in which my invention 1s adapted to be used consist of girders, com- -for the principal longitudinal members, these longitudinal members being held and braced in definite relation to each other by a lattice system of diagonal braces.

It is evident that the stresses upon such girders are located at and transmitted through the points at which the bracing members are attached. For this reason it is important that the strength of the principal longitudinals be not reduced at the points of attachment of the braces, but

rather that it be augmented by suitable reinforcement at such places in the structure.

It is the object of my invention so tol constructv the joints that this' reinforcement is effectedwithout the addition of superiuous material, an essential in structures. such as the framing ofl rigid. airships,

lightness, as well as stiffness and strength,

is desirable. I attain thisobj ect by the use of a fitting which is a. combination of straps and webs, in vconnection with bands or rings for holding the Various'partstogether.

In the accompanying drawings, Fig. 1

1, together with elevations of the ends of braces attached thereto. Similar reference numbers in the several figures refer to s imilar parts.

At 1 is shown the tubular member, to which-the strap or saddle 2 is fitted. A t

`55 are shown bands or collars, surroundsaddle The strap or in the tube 1, and sa dle 2 is provided with webs 3 3, formed integrally with it, and at such vangular relation as may be -desired to correspond with the direction intended ,for the attached braces The braces 4 4 are provided with flattened ends 7-7 as shown, enabling The ends of the strap or saddle 2`are madev v with a -slight taper,

-them to be attached to the webs 3-3 by4 At 6--6-6 are: shown dowel pins, riveted i to the strapl or saddle 2, the .cylindrical heads of which pins 6-6-6 engage with corresponding holes drilled in the tubular member 1.

These pms act to transmit the angular thrust of the braces H to the tubular member 1, and prevent the-strap or saddle 2 from shifting on the tubular member 1. The bands for collars 5-5 are shrunk or driven on the strap or saddle 2, v

and being made slightly tapering on the 1nside, the driving into position draws the saddle 2 firmlytothe tubular member 1. VThe bands or collars 5--5 may be further secured from sliding oi by any well.

known means.

The strap or 4saddle 2 may be formed as a y solid casting or' forging, 4or lmay be made a coupling member intermediate between the as shown in 4, this shaped out of sheet meta form `being bent or Itis evident that this method of fastening or connecting pipe members lof a framed structure does not detract from the strength 0f the tubular member 1, by the additional strength of the strap or saddle 2, and-the bands or hoops 5 5.
